That 100% there will only stretch the LI to the width of the parent container. You can use negative left/right margins to stretch it further, but CSS can't tell how far left and right it will need to stretch. For that, you'd need a bit of JS. PPK does something similar on his site: http://www.quirksmode.org/js/strings.html (notice how his <pre> elements stretch to the edge of the window on both sides).

Hi,

Not really sure what you want to happen there but the second and third items could be centred with margin:auto.
